The CAS Registry Mumber 15207-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,0 and 7 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 15207-15: (7*1)+(6*5)+(5*2)+(4*0)+(3*7)+(2*1)+(1*5)=75 75 % 10 = 5 So 15207-15-5 is a valid CAS Registry Number.
